如何为 Krea 2 写提示词

最重要的规则

1. 1

   只选一种风格和一种媒介

   每张图只用一种外观:“1990 年代赛璐珞动画”“微距摄影”“清线风格的平涂插画”。混用多种风格会让它们全都变得模糊。

2. 2

   让每个主体保留各自的细节

   把每个人物或物体连同它的属性和动作写在一起,这样红色外套才会穿在正确的人身上。

3. 3

   用平实的语言安排位置

   “她的左手搭在栏杆上”“左下前景中有一块深色岩石”。这类基于画面实景的写法,能确定姿势和布局。

4. 4

   描述画面里有什么

   在默认设置下,反向提示词不起作用。想排除某样东西时,不要列出要去掉的内容,而是写“一面空白的白墙”或“一片空无一人的海滩”。

5. 5

   用引号标出要显示的文字

   把文字放进双引号里,并保持简短:招牌、标签或标题。

可参考的提示词

• 一句简短的话

  immense rocket launch exhaust as seen from extremely close up

  为什么有效: Krea 2 会按自己的审美来扩展简短的想法。在写完整提示词之前,可以先用它来探索。

• 短语列表

  3D rendered matte black designer toy figure, stylized round anthropomorphic shape, backward black baseball cap, oversized gold-rimmed aviator sunglasses, white traditional line-art tattoos of a tiger and a bird on the torso, black studded belt with a gold buckle, smooth vinyl texture, studio lighting, solid vibrant blue background, high contrast minimal composition

  为什么有效: 先写媒介,所有属性都归属于同一个人物,最后以光线、背景和构图收尾。

• 内容丰富的段落

  A tiny russet-brown harvest mouse clings to a slender diagonal branch amid vibrant green lobed leaves and small round buds. The mouse has soft textured fur, glossy black eyes, a pink nose, fine whiskers, and delicate pink paws firmly gripping the wood. In this macro photograph, an extremely shallow depth of field sharply focuses on the animal's face. The deep green background dissolves into a smooth, creamy bokeh, lit by soft, diffused natural light that brings out the fur and foliage.

  为什么有效: 先写主体和它的动作,再写细节,然后是媒介、焦点和光线。适合搭配 3:2 的宽高比。

• 复古动漫

  1990s vintage anime style cel animation, densely packed crowd of teenagers in summer uniforms, central boy with short black hair raising a clenched right fist, squinting one eye with a determined expression, white short-sleeve shirt and solid green necktie, surrounding students looking in various directions, girls in white sailor blouses with green striped collars, light blue skirts and trousers, tightly framed medium shot, flat shading, soft muted retro palette

  为什么有效: 指定一种风格,一个主要人物及其细节写在一起,人群则作为一个整体只描述一次。可以试试 16:9。

• 把简短的想法扩写

  A minimalist flat-color illustration of a person wading through expansive shallow ocean waves beneath a pale peach sky. The dark-skinned figure, wearing an orange swim cap, a light blue top, and bright green shorts, steps carefully through knee-deep water. The ocean is muted mint green with thin black linework tracing the continuous ripples and gentle whitecaps, and soft pinkish-peach reflections echo the sky. A dark, jagged rock rests in the lower left foreground near a pale gray shoreline; the horizon holds a solid purplish-blue landmass and a stylized layered yellow and blue cloud. The high-angle wide perspective leaves vast negative space in the water, in a clean ligne claire style with a subtle paper texture.

  为什么有效: 由“在海里涉水的人,扁平插画”扩写而成:媒介仍是扁平插画,只选定一种取景和一套配色,每个元素都有自己的位置。
